Bifunctional aminoacyl-tRNA synthetase is an enzyme that in humans is encoded by the EPRS gene.^[5]^[6]

Gene[]

Alternative splicing has been observed for this gene, but the full-length nature and biological validity of the variant have not been determined.^[6]

Function[]

Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a multifunctional aminoacyl-tRNA synthetase that catalyzes the aminoacylation of glutamic acid and proline tRNA species.^[6]

Phosphorylation of EPRS is reported to be essential for the formation of GAIT (Gamma-interferon Activated Inhibitor of Translation) complex that regulates the translation of multiple genes in monocytes and macrophages.^[7]

Interactions[]

EPRS has been shown to interact with POU2F1,^[8] Heat shock protein 90kDa alpha (cytosolic), member A1^[9] and IARS.^[10]
